Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may connect with a base station over a set of component carriers according to a carrier aggregation configuration. The UE may then monitor a search space configured for scheduling multiple component carriers and may receive downlink control information (DCI) based on monitoring the search space. The DCI may include a carrier indicator field (CIF) and may schedule a set of data transmissions over two or more component carriers (e.g., from the set of component carriers). The UE may determine that the two or more component carriers include the first component carrier and the second component carrier based on the monitored search space, the CIF within the DCI, or both. The UE may then transmit and receive the set of data transmissions over the first and second component carriers.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station over a set of component carriers according to a carrier aggregation configuration. In some cases, the UE may receive an indication of one or more groups of units, where each group may include one or more component carriers and/or one or more time intervals of each component carrier. The UE may receive downlink control information (DCI) including one or more fields that are common to a group of units that may schedule a set of data transmissions over the one or more groups of units such that the single DCI may schedule multiple component carriers (e.g., two or more) over one or more time intervals. The UE may transmit or receive the set of data transmissions (e.g., uplink or downlink data transmissions) over the scheduled units based on receiving the DCI.

Abstract: Techniques are described for wireless communication. One method includes detecting a first reference signal received from a user equipment (UE) in a reference scheduled transmission burst including a plurality of contiguous transmission time intervals (TTIs) received over a shared radio frequency spectrum band; identifying a reference TTI in which the first reference signal is received; determining a contention window size usable by the UE to contend for access to the shared radio frequency spectrum band; and transmitting an indication of the determined contention window size to the UE.

Abstract: Improved methods, systems, devices, or apparatuses that support search space design are described. The described techniques enhance the number and utility of applied control channel candidates in the presence of blind decoding and control channel element (CCE) channel estimation limitations. The techniques allocate available blind decodes using a nested mapping scheme over one or more dimensions, based on a prioritization. In some other cases, the number of blind decodes may be allocated, either uniformly, or proportionally, between the plurality of search space set occasions. In some cases, the applied control channel candidates may be determined by dropping control channel candidates along one or more dimensions (e.g., search space set, or search space set occasion), until the blind decoding limitation or CE limitation is satisfied.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently facilitating acknowledgment (ACK) or negative acknowledgment (NACK) feedback from a user equipment (UE) for a set of transport blocks in one or more multicast transmissions from a base station. The UE may determine control channel resources for transmitting the ACK/NACK feedback, and each respective control channel resource may correspond to a distinct subset of the set of transport blocks. Once the UE determines a subset of transport blocks that the UE failed to decode (such as at least one transport block), the UE may determine a respective control channel resource that corresponds to the at least one transport block that the UE failed to decode. The UE may transmit ACK/NACK feedback on the respective control channel resource, which, in some examples, may indicate that the UE failed to decode the subset of transport blocks.

Abstract: Methods, systems, and devices for wireless communication are described. User equipment (UE) and base stations may support frequency hopping with fast retuning for enhanced machine type communication (eMTC). For example, a UE may need to retune portions of its receive or transmit chain to support operation on various frequency bands, and it may perform the retune within a few symbols. Both base station and UE may anticipate or account for the retuning delay and communicate accordingly. A base station may refrain from transmitting for a certain period of time, for example. A base station may also account for frequency hopping delays for uplink communications. Systems may employ other techniques to support eMTC. For example, UEs may leverage reference signal patterns in certain control channels for demodulation. In some cases, base stations may alter control channel transmissions to account for various types of UEs with in the system.

Abstract: Methods, systems, and devices for wireless communications are described. A child node may communicate in an integrated access and backhaul (IAB) communications system with a parent node and the parent node may transmit system information to the child node that may indicate one or more random access channel (RACH) procedure configurations such as a user equipment (UE)-specific RACH procedure configuration and a wireless backhaul-specific (e.g., TAB-specific) RACH procedure configuration. The child node may be configured to utilize the UE-specific RACH procedure configuration or the TAB-specific RACH procedure configuration such as if the child node meets one or more conditions or upon receiving an indication from the parent node. The child node may determine to use the UE-specific RACH procedure configuration for communicating with the parent node and may perform a RACH procedure with the parent node in accordance with the UE-specific RACH procedure configuration.

Abstract: Various aspects described herein relate to reducing transmission latency in unlicensed spectrum. These latency reduction techniques include enabling ultra low latency (ULL) traffic to gain fast channel access. These latency reduction techniques further include updating a size of a contention window for channel access. In addition, these latency reduction techniques include enhancing CPDCCH-based signaling to accommodate the ULL frame structure. Further, these latency reduction techniques include providing robust operation against bursty interference for ULL transmissions. Moreover, these techniques include managing DRX for ULL. Additionally, these latency reduction techniques include joint scheduling of different TTI durations. These latency reduction techniques further include updating SRS transmission opportunities. In addition, these latency reduction techniques include reducing latency associated with PRACH transmissions. Further, these latency reduction techniques include reducing ULL transmission delays by either ignoring or cancelling scheduled uplink (e.g., LTE) transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine whether to perform a simplified uplink control information (UCI) multiplexing procedure or select an overlapping uplink channel having the highest priority and drop the remaining overlapping uplink channels. The UE may determine that a first symbol period of the physical uplink scheduled channel (PUSCH) is aligned with a first symbol period of the physical uplink control channel (PUCCH) and the UE may multiplex UCI with an uplink data transmission. The UE may transmit the multiplexed UCI and uplink data on the PUSCH and drop the PUCCH. The UE may perform UCI multiplexing for overlapping PUCCH and PUSCH, located on the same component carrier (CC). The UE may refrain from performing UCI multiplexing if the PUSCH and the PUCCH are located on different CCs, and may simultaneously transmit UCI and uplink data over the different CCs.
